l'iLEV/XTR ATTACHMENT TO SHIPS GANG-PLATFORMS.

SPECIFICATION forming part of Letters Patent No, 288,109, dated November 6, 1883 Application filed May $36, 18H3. (No model.)

lo @ZZ whom t may concern,.-

Beit known that I, HENRY N. PnAnn., of EaGrange, in the county of Lee and State of Arkansas, have invented a new and Improved Elevator Attachment to Ships Stage or Gang Platforms, of which the following is a full, clear, and enactdescription.

My invention relates to an endless elevator attachment to stage or gang planks or platforms for steamboats and other vessels, to

by the use of steam-power, to be vapplied directly to the elevator shaft r drum by an en- Y gine or engines located on the stage, or through intermediate gearing connecting the elevator with a driving-engine located inv the hold or other part of the vessel; and the nature of my invention consists of the combinatiomwith the foregoing, of certain devices, all as hereinafter. fully described. y

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure lis a plan view of a gang-platform or stage with aprons attached at the ends, and with an endless elevator attachment according to my invention. Fig. 2 is a longi tudinal section 'of Fig. l on the line x x. Fig. 3 is a transverse section of Fig. l at the line y y; also a section of a portion of 'the deck of a stage, and an elevation of driving-gear for transmitting the power of an engine located in the hull of a vessel to the elevator onthe stage.

Along the middle portion. of the stage a or gang-platform I propose to arrange an endlessbelt or chain of lugs or slats, b, to runfrom end to end over a driving-drum, c, at one end, and a carrying-drum, e, at the other end, the said elevator or carrier being provided with rollers f, and the stage with angleironways g, for

the rollers to run on. rIhe stage may be constructed in any approved way; but I prefer to use four longitudinal stringere, 5, arranged at equal distances apart and connected by crossstays j, extending through all the stringers at the middle transversely, and duly fastened to them, and floorstays k, connecting the outer and intermediate stringers, respectively, leaving the space between the intermediate stringers free for the elevator.

To work the elevator thepower may be apq, with the shaft d of the drum c.

plied from a driving-shaft, Z, in the hold of the vessel, to which the engine may be connected in any approved Way, said shaft gearing by a bevel-pinion, m, with a wheel, a, on a tubular shaft, o, extending up through the deck p, and gearing by a pair of bevel-wheels,

For supporting the shaft o, and also for providing a bearing in which the end of shaft d may be readily fitted and detached as the stage is put in place and removed, I have a vertical shaft, s, xed in any suitable stand, t, in the bottom ofthe vessel, and extending up through shaft o,and to the upper deck, for its support, if desired, in which a bearing is provided for the/ end of shaft d, wherein said shaft may be placed and readily secured by a nut and washer, u, suitably applied to revolve with the shaft without disarrangement thereby, and so that the shaft may be pnt in and taken out readily. I propose, howevcr,`as before stated, to employ one or more engines located directly on the stage in any approved way, and having steam supplied through steam-hose, instead of the arrangement above described,whenever it may be preferred to do so 5 and this I propose toapply also to grading railroads, canals, and lawns, in the construction. of large buildings, and to such other purposes as it may prove suitable.

The stage will have the usual aprons, o and w, hooked on the ends, respectively, and over the upper one I propose to run an endless chain, w, from a shaft, y, to any other shaft, drum, or pulley-block attached anywhere on the vessel, to be used as an extension of the elevator b,when required, the shaft g/,whereby the said chain is driven by a suitable chainpulley, z, being provided with a toothed Wheel,` a', with which it is made to gear at anytime, as required, with the wheel b on vshaft d, byan intermediate Wheel, c', arranged to be shifted into and out of gear with said Wheels a b by a lever, e', or other means, as preferred.

Thus it will be seen that I have provided a simple and efficient contrivance for handling freight to load or unload steamboats and other vessels, it being understood that the elevator is to be geared to run either way at will.

The chains g are to be used to secure the stage at either or both ends.

, I propose to apply rollers h to the upper IOO endsfof the stringers "i, to rest on thin flat iron .2 esame tracks if., .arranged on the deck p, concentric with the shaft s, in order that the platform may be shifted or changed in position on the deck without being detached from shaft s; and I prefer to arrange said rollers in the aXis of the shaft d, by making them with hollow hubs or axes, and the shaft d to pass throughthem.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The platform having endless carrier b, drums c e, and rollers h', and being geared -with the hollow driving-shaft o, and arranged to shift or change position around said shaft without being disconnected from'it,"substan tially as described.

2. In a ships .stage or gang-platform having an endless carrier7 b, the drum c, having a projecting shaft, d, detaohably fitted in the
